Designation of an on-line monitoring system of transmission line´s galloping

Based on the analyses of the disadvantages and advantages of every on-line monitoring system of transmission line´s galloping, an on-line monitoring system of power transmission line´s galloping based on displacement sensors and acceleration sensors is developed in this paper, in which the wireless sensors network and the slave monitoring unit installed on towers are designed by wireless communication technique, by those monitoring units the galloping can be analyzed qualitatively and quantitatively. The operating principle, structure and function of the system are all analyzed at the same time. Moreover, the designation of the node of wireless sensors network based on ZigBee technique and the slave monitoring unit installed on towers are all shown in detailed in this paper. Based on the galloping mechanism as well as earlier data, the galloping is simulated in theory, and then some simulating results are shown in this paper at last.
